A54SX32A-2FGG484 概要
An FPGA (Field-Programmable Gate Array) is a semiconductor device that implements custom digital logic through programmable interconnect and configurable logic blocks. Within the programmable logic hierarchy, the A54SX32A belongs to the one-time-programmable antifuse FPGA category, positioned under FPGAs > programmable logic ICs > digital logic semiconductors. The SX-A family uses a sea-of-modules architecture in which the chip floor is a dense grid of logic modules, minimizing area lost to routing and enabling high gate utilization at low cost.
Key features of the A54SX32A-2FGG484 include 0.25 um CMOS antifuse technology, 2.5 V core operation with support for 2.5 V, 3.3 V, and 5 V compatible I/O standards across the SX-A family, speed grade -2 timing, and a 484-ball FBGA footprint shared across the SX32A/SX72A density range. The antifuse interconnect is non-volatile and inherently single-chip: no external configuration PROM or boot sequence is required, which reduces BOM cost, board area, and configuration-bitstream security exposure compared with SRAM FPGAs.
Architecturally, the device combines two logic module types: C-cells (combinatorial logic modules) and R-cells (register cells), embedded in a segmented routing fabric. Because antifuse links are programmed once at the factory-level programming stage, the device exhibits low static power, deterministic interconnect capacitance, and immunity to configuration upsets, making it attractive in harsh environments.
Typical applications include industrial control and automation logic, telecommunications line-card glue logic and protocol bridging, aerospace and defense data paths, and medical instrumentation where single-chip integration replaces multi-chip ASSP and discrete logic solutions.
Design consideration: because the SX-A is one-time programmable, prototype on the larger A54SX72A same-footprint device first and lock the design before committing programming; also budget I/O bank voltage selection (2.5/3.3/5 V) at layout time.
This page synthesizes distributor pricing (LCSC from $213.1034 as of 2026-09-03), same-footprint drop-in alternatives, and engineering design notes not found in the manufacturer datasheet.

主な用途
A54SX32A-2FGG484 の用途: 6 件s: Industrial Control and Automation, Telecommunications Line Cards, Aerospace and Defense Data Paths, Medical Instrumentation Control Logic, Legacy System Sustainment and BOM Rescue, Security-Critical Single-Chip Integration.
Industrial Control and Automation
In factory automation and industrial control, the A54SX32A-2FGG484 integrates interlock logic, encoder interfaces, and protocol glue logic into one 48,000-gate antifuse chip, replacing multiple discrete 74-series devices and reducing BOM count and failure points. Its 249 user I/Os accept 3.3 V and 5 V industrial signal levels, while the 313 MHz -2 speed grade comfortably covers PWM generation and safety interlock timing. The -I industrial variant is rated -40C to +85C for cabinet environments. Because antifuse configuration is non-volatile, the controller is instantly active at power-up with no configuration PROM that could be disturbed by electrical noise on the factory floor.
おすすめ
Telecommunications Line Cards
Telecom line cards use the A54SX32A-2FGG484 for protocol bridging, framing logic, and backplane interface glue logic. The 0.25 um CMOS antifuse fabric provides deterministic interconnect delay, which simplifies meeting fixed T1/E1 or SONET framers' timing windows, and the 2880 logic cells fit counters, shift registers, and state machines typical of line-card supervisory logic. The 484-ball FBGA's fine-pitch ball grid suits high-layer-count telecom boards, and the antifuse fabric's low static power reduces line-card thermal budget. Its single-chip, no-boot behavior ensures the card is operational immediately after hot-swap power sequencing, a key advantage over SRAM FPGAs that need configuration loading time.
おすすめ
Aerospace and Defense Data Paths
Actel antifuse FPGAs are a traditional choice in aerospace and defense due to their configuration-upset immunity: there is no SRAM configuration memory to corrupt under radiation or hostile electrical conditions. The A54SX32A-2FGG484 implements data formatting, bus interfaces, and telemetry logic in 48K gates with 249 I/Os, and its non-volatile antifuse bitstream is inherently difficult to read out, supporting design security requirements. The 2.5 V core keeps static power low for conduction-cooled enclosures, while the 313 MHz -2 grade handles high-rate serial framing. Design teams value the deterministic timing that antifuse routing provides for certification analysis and worst-case timing sign-off.
おすすめ
Medical Instrumentation Control Logic
Medical diagnostic and monitoring instruments use the A54SX32A-2FGG484 for sensor timing, acquisition sequencing, and host interface logic. The 48,000-gate capacity integrates the control state machines and data-path multiplexing that would otherwise occupy several PLDs, supporting compact instrument designs. Antifuse one-time programming guarantees the shipped configuration cannot drift or be altered in the field, an attribute relevant to regulated medical device change control and software configuration management. With 5 V-tolerant I/O options on the SX-A family, the device interfaces directly with legacy analog front-end boards, and the instant-on behavior removes boot latency from time-critical measurement chains.
おすすめ
Legacy System Sustainment and BOM Rescue
Many fielded systems were designed around SX-A antifuse FPGAs and still require exact silicon for spares and continuing production. The A54SX32A-2FGG484 serves legacy sustainment programs where redesign onto modern FPGAs is not economically justified. Because the 484-ball FBGA footprint is shared across the SX32A and SX72A densities, buyers can substitute A54SX72A-2FGG484 during shortages without PCB rework, only recompiling the design in Libero with updated timing constraints. Distributors including LCSC and Microchip USA stock these parts specifically for obsolescence-risk mitigation, making this device a common line item in long-tail BOM procurement lists.
おすすめ
Security-Critical Single-Chip Integration
Applications that must prevent design theft use the A54SX32A-2FGG484 because antifuse configuration data is buried in programmed links rather than stored in an external flash or SRAM bitstream. There is no configuration device to intercept, no bitstream upload to snoop, and no readback path typical of SRAM FPGAs, which protects proprietary logic and encryption wrappers. The 48K-gate capacity is sufficient for bus encryption, authentication state machines, and board-level access control logic, while 249 I/Os cover wide system buses. Systems needing instant-on secure operation, such as secure network appliances, also benefit from the absence of a boot-time configuration window.

設計ノート
Plan dual-rail power: 2.5 V for the core plus the chosen I/O bank voltage (2.5 V, 3.3 V, or 5 V). The SX-A family supports 2.25 V to 5.25 V supply range per Microchip USA product data. Because antifuse FPGAs have low static current, modest LDOs typically suffice for the core rail, but check worst-case dynamic current at 313 MHz toggle rates in Libero power analysis. Estimated: core dynamic power scales linearly with toggle frequency and logic utilization, so derate at high utilization.
The SX-A is one-time programmable: a bad bitstream consumes the device. Prototype and validate on the same-footprint A54SX72A-2FGG484 first, then program A54SX32A-2FGG484 production units only after timing sign-off in Libero IDE. Also lock I/O bank voltage selection before layout; changing I/O standards later may invalidate the ballout assignments on the 484-ball FBGA and force board respin.
The 484-ball FBGA (27x27 mm, fine pitch) requires controlled-impedance escape routing with via-in-pad or dogbone fanout on high-layer-count boards. Place 100 nF ceramic decoupling capacitors on each power ball group, plus bulk 10 uF per rail. Ball A1 (pin 1) is at the chamfered corner; verify orientation against the datasheet ballout table before generating the footprint to prevent 180-degree rotation errors.
